Back Wank 

The act of placing the penis between your legs so that it protrudes behind you and then masturbating. You are then able to observe yourself in a mirror and it will look as if you have a minge. You may then imagine that this minge belongs to the female of your choice. This can be handy if no pornography is available and the bishop is asking for a bashing.

I had to wank last night and my wife had chucked all my porn. So I had a back wank and pretend I was looking at Kate Moss.

Back handed scuttle wank 

When you reverse the hand when masturbating.

When I masturbate I like to turn my hand around and have a back handed scuttle wank.

backwank 

To get revenge on a partners refusal to participitate in sexyness - once the said partypooper is asleep unleash hellfire and throw arcings rope of jism upon her unsuspecting bare back.

Rob - "Did you and Fran get rude last night ?"

Steve - "No, the bitch wasnt interested - had to settle for a backwank instead! Her back's as smooth as an eel now!"
